虽然贝壳丘和贝壳丘经常占据与海岸湿地相同的潮间带空间，但这些文化特征与湿地之间的生物物理相互作用尚未得到充分研究。为此，我们在美国坦帕湾河口的三个沿海考古遗址进行了地质考古和动物考古研究，试图了解贝壳遗址、海平面上升、风暴和迁徙湿地栖息地之间的相互作用。敲击核样带记录了完整的贝壳丘上红树林泥炭的增生，说明了红树林侵蚀贝壳丘和保存下面文化物质的能力。向陆地的湿地沉积物比向海边缘的沉积物更厚、更泥泞，这表明壳类遗址像其他海岸线稳定结构一样衰减波浪能量。沉积学、地层学和无脊椎动物物种组成的差异突出了不同地点之间风暴影响的可变性。风暴驱动的沉积事件由具有高密度破碎壳和小潮间带螺的中细砂层确定。地理空间分析表明，坦帕湾河口的247个考古遗址已经发生了湿地侵蚀。目前大约有100个额外的考古遗址位于高地栖息地，将来可能会为迁移的沿海湿地提供地形缓解。我们认为，土著人民建造的贝壳丘和土丘是河口景观的重要组成部分，几千年来一直如此。我们提倡考古学家和河口管理者之间的进一步合作，并包括后代社区，共同管理他们过去的未来。
Although shell middens and mounds often occupy the same intertidal spaces as coastal wetlands, biophysical interactions between these cultural features and wetlands are under-investigated. To this end, our geoarchaeological and zooarchaeological research at three coastal archaeological sites within the Tampa Bay Estuary, USA, sought to understand the interactions between shell-bearing sites, sea-level rise, storms, and migrating wetland habitats. Percussion core transects document the accretion of mangrove peat atop intact shell midden, illustrating the ability of mangrove forests to encroach shell midden and preserve cultural material below. Landward wetland deposits are thicker and muddier than those along the seaward margin of the sites, suggesting that shell-bearing sites attenuate wave energy much like other shoreline stabilization structures. Differences in sedimentology, stratigraphy, and invertebrate species compositions highlight the variability in storm impacts between sites. Storm-driven depositional events are identified by medium-to-fine sand beds with high densities of fragmented shell and small intertidal zone snails. Geospatial analyses indicate that wetland encroachment is already occurring at 247 archaeological sites within the Tampa Bay Estuary. Approximately 100 additional archaeological sites currently located in upland habitats may provide topographic relief for migrating coastal wetlands in the future. We contend that shell middens and mounds constructed by Indigenous peoples are important components within estuarine mosaics, as they have been for millennia. We advocate for further collaboration between archaeologists and estuary managers and the inclusion of descendant communities to co-manage the future of their past.
